General markings:
Use 60/75 °C or 75 °C copper wire only.
ƒ
Maximum ambient temperature 55 °C, with reduced output current.
ƒ
Markings provided for the supply units:
Suitable for use on a circuit capable of delivering not more than 5000 rms
ƒ
symmetrical amperes, 480 V max, when protected by K5 or H Fuses
(400/480 V devices).
Alternate - Circuit breakers (either inverse-time, instantaneous trip types or
ƒ
combination motor controller type E) may be used in lieu of above fuses
when it is shown that the let-through energy (i
current (I ) of the inverse-time current-limiting circuit breaker will be less
p
than that of the non-semiconductor type K5 fuses with which the drive has
been tested.
Alternate - An inverse-time circuit breaker may be used, sized upon the
ƒ
input rating of the drive, multiplied by 300 %.
Markings provided for the inverter units:
The inverter units shall be used with supply units which are provided with
ƒ
overvoltage devices or systems in accordance with UL840 2nd ed., Table 5.1.
The devices are provided with integral overload and integral thermal
ƒ
protection for the motor.
The devices are not provided with overspeed protection.
